The sewer in the garage on the first floor of my house was flooded and the property was blocked by them. My home is on the second floor, and the water in the toilet will go back to my home.

The sewer belongs to the use part of * * *, and this matter should be the responsibility of the property management company. It is not good for the property management company to directly block it if it does not clear it. At least find out the problem and ensure that it will not affect other owners.

If the whole dredging cost or decoration cost is too high, you can apply for a maintenance fund (the maintenance fund was paid by the owner when buying a house, and the developer also paid part of it).

If the property management company doesn't take this matter seriously, you can report it to the competent department of the property management company, such as the local property management association or the Housing Authority.
